It's a total of 100 half watts, Bridge rectifier is making AC to DC, they could be dimmable if I really wanted them to be. I've been doing research on all this stuff for the last 4 to 6 months. I have a LFS that wants to sell my product already and we haven't even started producing them yet. I'm pretty excited but don't want to get my hopes up till things are well. Thanks for the questions and the link! Oh and by the way they are cree LEDs.
